From the window of a building, a ball is tossed from a height h above the ground with an initial velocity of v 8.00 m/s and angle of 20.0° below the horizontal. It strikes the ground 3.00 s later. If the base of the building is taken to be the origin of the coordinates, with upward the positive y-direction. Following the following steps to determine: 1. How far horizontally from the base of the building does the ball strike the ground? Find the height from which the ball was thrown. 2. a) b) c) [10% ] What is the initial position x-comp and y-comp? [20% ] What is the initial velocity x-comp and y-comp? [5%] Write the following equations: VxfVxi xf = x₁ + xit H Vyf Vyt - gt Yr Y₁+ Vyit - 1 2 gt² d) [40% ] Input the values from above a) to b). [what is final y-position of the stone?] Then you should able to find: e) [15%] the height from which the ball was thrown. f) [15%] the horizontal distance from the base of the building to the ball strike the ground. follow the order a), b), Your answers must not more than one line No detail numerical calculation procedures is needed.
